Dialogue system and a dialogue method

A dialogue system, comprising:

• an input configured to obtain input data relating to speech or text provided by a user;
• an output configured to provide output data relating to speech or text to a user;
• one or more processors, configured to:
• receive, byway of the input, input data relating to speech or text provided by a user;
• provide the input data to a first module, the first module comprising a subject understanding module, wherein the subject understanding module comprises one or more subject understanding models, each of the one or more subject understanding models configured to take as input the input data and provide as output subject profile information;
• generate a system input using the subject profile information;
• provide the system input to a language model, the language model configured to provide a system response;
• and
• output, by way of the output, the system response,
• wherein the one or more processors are further configured to provide the input data to a subject safety module and evaluate the input data before a system response is output, wherein the subject safety module is further configured to prevent output of the system response depending on the output of the evaluation.

A dialogue method, comprising:

• receiving, by way of the input, input data relating to speech or text provided by a user;
• providing the input data to a subject safety module, the subject safety module configured to receive the input data and evaluate the input data before a system response is output, evaluating the input data comprising performing a first determination on the input data using a matching module and a second determination on the input data using a trained model, wherein the matching module performs the first determination to determine whether the input data matches one or more items from a pre-determined set of one or more items;
• generating a system response using a first process or using a second process, wherein the first process uses at least one trained language model to generate a dynamically determined system response and wherein the second process retrieves a pre-determined system response, wherein a selection between the first process and the second process is made based on the evaluation of the input data;
• outputting, by way of the output, the system response.

A dialogue system, comprising:

• an input configured to obtain input data relating to speech or text provided by a user;
• an output configured to provide output data relating to speech or text to a user;
• and
• one or more processors, configured to:
• receive, byway of the input, input data relating to speech or text provided by a user;
• generate a first system response from the input data using a first trained model;
• provide the first system response to an output safety module, wherein the output safety module is configured to evaluate the first system response and provide an evaluation result;
• responsive to a first evaluation result, output, by way of the output, the first system response;
• responsive to a second evaluation result, generate a second system response;
• output, by way of the output, the second system response.

• provide the system input to a language model, the language model configured to provide a system response;
• and
• output, by way of the output, the system response,
• wherein the one or more processors are further configured to provide the system response to an output safety module, wherein the output safety module is configured to receive the system response from the language model and evaluate the system response before it is output.

• responsive to a second evaluation result, generating a second system response;
• outputting, by way of the output, the second system response.
